SPRING eiserne,

To all whom it may concern.: 7 B e it lknown that 'NORMAN E. Gila acitizen of ,the Unit-ed States, residing at Altoona,

in the vcounty of Blairand State of Pennsyl- Vania,` has inventedVcertain -new Vand Vuseful Improvements in Spring Rigging, of whichwherein the driving motors arev placedahead of` the driving wheels, andit is desirable that thevweight on'the front truck be equalized withthatv on thedriving wheels.

Another object of this invention is to provide means forkeepingthespr-ing'geariin alignment with the equalizers which are poyAfnrtheriobjectof thisiiivention'is to provide means for'breaking up theequalization'onone end off the locomotive such asv toY form' `a threepoint .suspension :forthe weight carried by theV springs,v thus giving'alocomotive .spring rigging constructionl tl'iatv readilyj adapts itselfto .the safe operation o ftloc'omotives athigh speeds.

l A still further-@object of this invention is Vto provide a commonfulcrum pinfor a system of cross equalizers between Athe means designedto carry the weight onthefront truck Aand toV transfer apart of theweight to the driving wheels and the Vmeans designed to carry the weighton the main driving wheels of the locomotive.l Y With these andmanyother objects in view the same consists in the novel construction,combination, and arrangement ofv parts illustrated and claimed.` i f Itwill be quite readily understoodfby those skilled in the art to which`this invention belongs that the same isquite suscepvtibleto somestructural changes and modifi'- cations without departing Vfrom thespirit or scope of the invention,- but apreferred and Figurev 2 shows across sectional viewV taken on the line 3-3 of Figurel.

lbut as'thef locomotive iframe which envelopes the motors is madenecessarily low withv reference to the rail 'it becomes imperativeto ydevise other means than Atheusual equalizer which passes beneath thecylinder saddle on l i steam locomotives, in order that' the saine*yequalization canrbe afforded an electric loco.v motive wherein thedriving motors are positioned ahead of the driving wheels andback i ofthe truck or pony wheels, 'and to this-'end .a bell crank, designated bythe numeral 10, as will be hereinafter fully pointed out,-

The horizontal arm 23 of the bell crank 2l is adapted to beattached through a gib connection 2li to a hanger 25 which has a pinconnection 25A with a cross equal-y spring 33 is ot the usual design,and presents no new features that vention. y Y

Equalizer 34 which is positioned above the driving box of the lastdriving wheel is shown as having one end thereof, attached to an helicalspring 35 which rests on the frame as shown in Figure l of the drawings.

The opposite end 36 of the equalizer-.34:

are a part of this in- `is provided with a hanger 37, to which isattached a pendent clevis 38, the lower end of which is adapted toengage an end 39 of the bell crank arm 23 as shown in Figures 1 and 6 ofthe drawings. c

In the adoption ofi this design of spring gear to a locomotive of thetype it is necessary to biu'rcate the end 40 of the pedestal cap 41. Thelower -ba'r 42 of the frame is likewise separated to permit thepassageof the bell crank arm, as shown in Figures 2,

3 and 4t of the drawings.

Having thus describedmy invention whatV i l claim and desire to besecured by Letters Patent is- 1. The combination spring rigging, ofmeans for equalizing the weight carried by the front trucks with theweight carried by the main drivers, said mea-ns including a plurality otcross equalizers. each having a common pin connection.

2. The combination with a locomotive truck and spring rigging, of aplurality of equalizers positioned on either side of the locomotive andon either side of the locomo tive trame, means 'for transferring theweight carried by the spring ri'ggingto the driving box of thelocomotive, a plurality ot cross equalizers having a common pinconnection, and means for transferring a portion ot the weight carriedbythe truck to the frontdrivers.

3. In combination with a locomotive spring rigging, springs,equa-liners. bell cranks, and spring hangers a system of crossequalization incombination with bell cranks at one end of the locomotiveand a combination ofV bell cranks without the cross equal- .izers at theopposite end of the locomotive.`

upper and lower frame bars, a. bifurcated lower bar for the frame, a-frame cap one end of which is bifurcated to conform with the frame, abell crank adapted to move` NORMAN E. one.
